Dreadlocks do tend to pick up lint and fuzzy’s even if they are very clean. This is usually a big problem when you are sleeping. Pillow cases and sheets that don’t shed a lot of lint will help. Wearing a head scarf on your head will keep lint and feathers out of your locs while allowing your dreads and scalp to breathe. Head scarves also have plenty of room for longer dreads to stretch out and they can be bought larger so they don’t squish your dreadlocks down too much.
